if I come visit early December is there a chance that there is not enough snow to ski in back to hotel?
Yes that could be a possibility. It all depends how much snow the mountains receive this year.
I know that we are already getting snow in Mammoth & the Sierra Nevadas right now, I'd check and see what's happening there & how the snow pack is. I've always been in Mid January. Always enough to ski.
Sorry, we visited there in June. There was still some snow visible in crevices. I suggest you call the hotel.
